` coking chambers 1 ing channels 12 (Figs. 3 aiid 5). The other chamber27 of each regenerator 20 is connected at the bottom by means of achannel 31 (Fig. 6) containing a cut-ofi valve 32, with a flue 33vleading to a reversing valve 34 (Fig. 1) located at the left hand sideof the oven adjacent to one of its ends.

Inan analogous manner the chamber 28 of cach let hand regenerator 21 isconnected at the bottom by a channelv 35 with one oi the verticalcollecting channels 13, While the other regenerator chamber E29communicates at its lower end by means of a channel 37 controlled by avalve 36, with a flue 38 likewise leading to the reversing valve 34.This reversing valve is secured to a shaft 39 which by means of a lever4() (Fig. 2) can be turned from the position indicated in Fig. 1 to thereversing position, in the well-l nown manner. According the valve 34occupies one or the other position, .it either connects the flue ivithan air inlet 41 and the tine withv a smoke line 42 leading to thestack', or the flue 'lfwith the smoke flue 42 and the fluo 38 with vtheair inlet 41. To regulate the total amount of air required by the benchvof ovens, I provide a valve 5G secured to ascrew spindle 49 and`located above the air inlet 41, said valve being adpistable vert1-cally by means of a hand lever 51 secured to the spindle, to vary theeffective cross sectio'n of the air inlet 41.

The coking chambers are'filled with coal through top opening normallyclosed by covers or 'plugs 43, while the colte is removed.throughopenings at the bottom, normally closed by plates 44. The gasproduced in the passes through the conduits 45 (Fig. 6) at the left ofthe ovens to the condenser 46. At the right hand of the ovens there areconduits 53, which may be .blosed by means of removable covers 52 andwhich serve for the escape of the gases at the termination of thecolring operation and at thetirne of filling the oven chambers 1.' Theovens rest upon pillars 4i' (Fig. 1) be tween which is left a space 48(Fig. (i) for the passage of the cars used to carry away the coke. Thepartitions 2 are supported by beams 19 resting on the foundation.

The operation of the oven is as follows: W hen the coking chambers 1 areheated from the riv lit-hand side ofthe oven, as indicated in tiedrawings by arrows, the gas valves 7 (Fig. 6) are open and the gasvalves 10 closed, the reversing valve 34 being in theposition indicatedin Fig. 1. ln this case gas enters each of the heating (lues 8 throughthe corresponding burner 4 (Fig. 4) While the air for supportingcombustion is eonveyed to both sets of heating flues 3 of each.partition 2 from the common collecting channel 12 through'the branchchannels '1 4'.

The combustion ga.. travel through theA "i heating lues 3 but once, fromright. to le tion.

and in so doing give olf most of their heat to the coking chambers 1.The still considerable heat then remaining in the combustion gases isthen carried away with them through the branch channels 15 totherespective collecting channels 13 and thence through the short channels35 into the corresponding upright regeneratorsr 21 arranged immediatelyadjacent to the individual coking chambers 1. lt will be 'seen that theheating gases do not have' to pass through .any long connecting channelson their way from the heating flues to the ie'generators, so that lavoid losses o'f heat which would result from the employment of suchlong channels. Thus that portion of the heat contained in the heatinggases which has not been absorbed by the coking chambers will bedelivered almost in full to the regenerators and by them transferredagain to the incomingr air intended to support oombus tion, after thedirection` of` the gas and air currents has been reversed;

ln each regenerator the combustion gases travel upward in the innerchamber 28 and downward in the outer chamber Q9. By subdividing eachregenerator into two chambers I provide for the combustion gases a longpath of comparatively small cross-sec- In passing through theregenerator chambers 28, v29, the combustion gases 've olf the heatcontained in them to the chec erwork of the regenerators, with theexception of a remnant such as is required to insure a proper draft inthe stack. The waste gases traveling through the regenerators 21 do notheat the coking chambers 1, but simply main tain the temperatureprevailing within the oven. In order not to interfere with a uni formoperation of the oven, the hot waste gases enter at the bottom of eachof the inner regenerator chambers 28, that is the chambers nearest tothe cokng chambers, so that duringY their upward travel in saidchambers, they will lose heat., corresponding to the upward decrease ofheat `wit-hin the oven. The waste gases, after passing through the outerregencrator chamber 29 from top to bottoni, reach the flue 38 throu hthe channel 37 and finally travel through t 1e smoke lue 42 leading tothe stack.

At the same time, the air for supporting combustion enters throughtheinlet 41 into the flue 33 and then passes through the channels 31 intothe regenerators 20. Through each of these regenerutors the air passesin a direction opposite to that of the passage of the waste gasesthrough said regenerator during the operation period immediatelypreceding. During its travel through the rcgenerators, the air absorbsthe heat stored therein. The highly heated air then passes from eachregenerator 2U to the corresponding collecting channel 12 through thechannel 30.

thus the Lesina? Reversai oi the operation is eti-ected by throwing thevalve 34 into its other position and by closing the gas valves 7 andopening the gas valves l0. This will cause the heating gases to travelthrough the ues in the direction opposite to that indicated by thearrows in Fig. a, While the regenerators 21 serve to preh-eat the airintended to support combustion and the regenerators 20 are heated by theWaste gases.

ery important advantages secured by certain features in the relativearrangement of the coling chambers. 'the heating fines, and theregenerators. Thus, the regenerators are loc-ated at the end of the oven(adjacent to the short sides oi the reotangnlar ooking chambers) Whilethe (horizontal) heating fines are disposed between the colring chambers(adjacent to the lone" sides of said chambers). I ain thus enabled toplace the colina-chambers very close together, since the' partitionsbetween theni contain only the heating iiue Another advantage resu tsfrom the fact that regenerators and heating,` fines are not adjacent toeach other, but located in different walls; y walls et the heating iiuesare not likely to crack, but even if they should, the combustion gasesescaping through suoli Cracks would have to travel a. comparatively ongdistance in order to reach the. regenen ators. The heating Walls orpartitions are noty attested by the periodical heating and cooling ot'the regenerators. and tlias the eating of the colting chambers is veryuniform. In my improved oven, each of the heating Walls has its own setot regenerators and it is therefore a very simple matter to regulate theheating;T action of each Wall individually, or even to stop the heat-.ing action entirely for any one ot the' heating Walis, which is a greatconvenience in making repairs. in order that individual regenerators maybe provided for each heating Wall, the upright arrangement has beenadopted for such regenerators-- The regencrators 20, 2l may be Inodiedby omitting the partitions 2a, 25, that in this case each regeneratorwiil have a single chamber. The collecting channels l2, 13

would then be connected with the upper ends of the regene ators 20, nels3i. would 2l, While the Chain be connected with the f nerators, asdescribed. f on7 tte air for supporting coin-bastion would pass throughthe regeneratoi but @noe from the bottoi l the tot), and after reversalthe Water would pass through the regenerators but once, from top tobottoni. This inodiiication and others may be niade Withoutdepartingtroni the nature of nay invention as defined in the appcndedclaims.
